A cell wall is a tough, flexible, and sometimes fairly rigid layer surrounding a cell.
The cell wall is one of the features of a plant cell that distinquishes them from animal cells.
The wall protects the plant cell, maintauns its shape, and prevents excessive uptake of water. On level of the whole plant, the strong walls of specialized cells hold the plant up againest the force of gravity.
The cell wall is made up of cellulose.They are a feature of plant cells.Mature cells add substances to the primary cell wall for additional strength or to make it waterproof.The fibres of cell walls are laid down in different directions to add strength. Cell walls contain other substances making a tough matrix. There is a "glue" between the cell walls of adjacent cells. Cell walls work with the vacuole to make a cell turgid and to help support the plant. Animal cells do not have a cell wall.The cell wall is non-living secertion of the cell membrane, composed of the cellulose.The cell wall provides protection from physical injury. The cell wall together with vacuole, provides skeletal support.The cell wall extracellular structure surrounding plasma membrane.The cell wall is composed of cellulose fiber, polyasaccharides, and proteins. The cell wall serves a similar purpose in those organisms that possess them. Most cell walls are porous enough to allow water, oxygen, carbon dioxide, and other substances to pass through easily.
